Divisibility Rule of 343

The divisibility rule for 343 is a method by which we can find out if a number is divisible by 343 or not without using the division method. Check whether 2401 is divisible by 343 with the divisibility rule.

Step 1: Check the last three digits of the number. Here, in 2401, the last three digits are 401.

Step 2: Check whether the number formed by these three digits, 401, is divisible by 343.

Step 3: Since 401 is not a multiple of 343, 2401 is not divisible by 343. If the result from Step 2 isn't a multiple of 343, then the number isn't divisible by 343.

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 343.

Know the multiples of 343:  

Memorize the multiples of 343 (343, 686, 1029, 1372... etc.) to quickly check divisibility. If the three-digit number is a multiple of 343, then the number is divisible by 343.

Use the division method to verify:  

Students can use the division method as a way to verify and cross-check their results. This will help them to verify and also learn.
